Machine Settings & AdjustmentsWARNING: Before working on any component of an attached machine, ensure that thetractor engine is turned off and the starter key removed to prevent anyone else fromstarting the tractor whilst it is being worked on.WARNING: Always ‘park up’ on a suitable firm, level surface with the parking brake applied, and ensurethe machine has come to a complete stop before adjusting or setting the machine.WARNING: Before attempting to access the underside of the machine, ensure it is adequately and safelysupported. Do not rely on the tractor’s hydraulics. Use safety supports that have a minimum SafeWorking Load (SWL) of 1.5 tonnes.Cutting Height AdjustmentThe cutting height of the pasture topper can be adjusted to cut at heights from 30mm to150mm. This is achieved by moving the bolt-on skids at each side of the machine to thedesired height position – see photo below.WARNING: Request assistance when removing and replacing the skids, they are heavy andmay cause injury.To adjust the cutting height: Raise the machine on the tractor lift arms and support it on suitable safety supports. Remove the nuts, bolts and washers securing the skid to the machine. Reposition the skid to the new desired position; use the cutting height decals on the sideof the machine (indicated in the photo above) as a guide. Fit and tighten all nuts and bolts securely, see ‘Torque Settings’. Repeat the process for the other skid, ensuring that both skids are at the same heightsetting. Raise the machine on the lift arms and remove the safety supports.Re-try the machine and re-adjust the skid height if the cutting height is still not suitable.29
